  language java theme Confluence
  private void button_buttonClick(Button.ClickEvent event) { Window popup = PopupWindow.For(new ProgressView()).closable(false).draggable(false).resizable(false).modal(true).show(); UI.getCurrent().push(); // Start your process here popup.close(); }

  Select XdevProgressBar > Properties > Indeterminate in the ProgressView.
  

• Dynamically update XdevProgressBar - Shows the current progress in the XdevProgressBar. The entire process must run in a separate thread. Since the thread runs on the server and the XdevProgressBar in the browser is not connected to does not get any information about it, a server push must be executed for every update of the XdevProgressBar through the invoking of getUI().access(()→progressBar.setValue(value)); method.

  Code Block
  language java theme Confluence
  private void progressBar_attach(ClientConnector.AttachEvent event) { // Find out the lenght of your process in total. The value is 1.0. // Starts a new thread on the serverside Runnable task = ()->{ // Start your process. Find out the current progress and store it in 'value'. Value must be between 0.1 and 1.0. // Server Push to update in the ProgressBar in the Browser getUI().access(()->progressBar.setValue(value)); }; new Thread(new RunnableAccessWrapper(task)).start(); }
